RAID कैलकुलेटर.
RAID 0, 1, 5, 6, 10, 50, 60 और ZFS RAIDZ के लिए उपयोगी क्षमता, दक्षता, फ़ॉल्ट टॉलरेंस, IOPS, थ्रूपुट और रीबिल्ड समय निकालें।
Hard drives under production load often rebuild at 50–150 MB/s.

- RAID protects against drive failure, not deletion, ransomware, fire or controller faults. Keep separate backups.
- Drive makers use decimal terabytes (10¹² bytes); operating systems often show binary TiB.

अंग्रेज़ी में तकनीकी जानकारी
Assumes identical drives. ZFS padding and slop space, controller caches and filesystem overhead are not included. RAID is not a backup. Everything is calculated in your browser; nothing is sent or probed on the network.
Usable capacity = data drives × size. Mixed IOPS = raw IOPS × read % + raw IOPS × write % ÷ write penalty. A RAIDZ vdev delivers about one drive’s random IOPS. Rebuild time = drive size ÷ rebuild speed.
8 × 16 TB drives in RAID 6 give 96 TB (87.3 TiB) usable, survive 2 drive failures and rebuild one drive in about 44 hours at 100 MB/s.
